About this trial

This randomized crossover trial will examine the acute effects of pre-exercise coherence breathing on cardiopulmonary exercise responses in recreationally active adults. Participants will complete two experimental conditions in randomized order: 5 minutes of guided coherence breathing and 5 minutes of quiet seated spontaneous breathing. Following each condition, participants will perform a standardized treadmill warm-up and a maximal cardiopulmonary exercise test. Outcomes will include oxygen consumption, heart rate, heart rate recovery, perceived exertion, time to completion, and heart rate variability. The findings may help determine whether coherence breathing can serve as an effective autonomic priming strategy before a bout of maximal exercise

Able to perform maximal cardiopulmonary exercise testing on a treadmill.

Disqualifiers

Accumulate less than 3 hours per week of moderate-to-vigorous physical activity.

Crossover

Treatments tested in this trial

  • Coherence Breathing

    Behavioral

    Participants complete 5 minutes of guided coherence breathing which consists or around 6 breathing cycles (5 seconds inhale and 5 seconds exhale)

  • Spontaneous Breathing

    Behavioral

    Participants sit quietly for 5 minutes with their regular spontaneous breathing

Treatment groups

20 Participants
are divided into 2 treatment groups
Group A: Coherence BreathingExperimental treatment 1 intervention
Group B: Spontaneous BreathingActive comparator 1 intervention

Trial outcomes

Primary outcomes

1

Peak Oxygen consumption

Peak oxygen consumption measured during the maximal cardiopulmonary exercise test (CPET) using a portable metabolic analyzer (Vo2 Master)

Time frame
during each maximal exercise test immediately after the breathing condition

Secondary outcomes

1

rating of perceived exertion (RPE)

using the RPE borg scale (from 1-10)

Time frame
measured at baseline, during the exercise test and after recovery
2

Heart Rate Recovery

Heart Rate (bpm) immediately after completing the CPET over a period of 5 minutes

Time frame
difference between peak HR during CPET and HR at minute 1, minute 2 and minute 5 of recovery.
3

Time to completion of maximal exercise test

total duration of the exercise test since test starts to voluntary termination

Time frame
during the exercise test
4

Peak Heart Rate

maximal heart rate achieved during the maximal exercise test

Time frame
measured during the maximal exercise test
